John was very knowledgeable, professional and helpful in every possible way in selling our Warren home. He really went above and beyond providing help with his valuable resources. He even spent time with many trips to storage for us. The whole family was very grateful for John's help in making this selling experience a successful one.

At a time when my mom was ill and needed to move with my dad to an apartment closer to where I lived so I could take better care of mom, Debra got straight to work finding that place. She was responsive, nimble, and compassionate. She worked hard to ensure my parents moved to a safe, beautiful place, just down the street from me!. I'll forever be grateful for her. She was stellar . - Anna

Chris was a pleasure to work with. He understood what we were looking for in a home, and went out his way to find listings and adjust his schedule to meet us for viewings. Chris is extremely knowledgeable about the real estate market, and he's well versed in home maintenance and minor renovations (if a home needed to be adapted.) Chris is diligent, competent, and he was attentive to our needs - a real pro and an extremely nice guy!

From our very first meeting, I was confident Roseann was the right broker to help us sell our home. Once we decided to move forward with her, she didn’t just meet our expectations—she exceeded them. Roseann was consistently punctual, responsive, and attentive. Whether by phone, text, or email, she communicated promptly and clearly, always providing thoughtful answers to our questions.
Her communication skills are exceptional, and her depth of knowledge in real estate is evident. She’s not only highly competent, but also empathetic and accessible. Those qualities made a stressful process feel manageable. Roseann’s dedication made us feel like we were her only client, and that level of personal attention is rare.
She is, without question, the epitome of what you hope for in an elite real estate professional.

Deb has been a dream to work with and work alongside of. There was an instant connection and comfort that, even though she is a wealth of knowledge and this is her field, she makes it a completely safe space to ask questions (sometimes five times over) while patiently acknowledging and explaining. She supported our family every step of the way. As much as I did not want to take advantage of her flexibility and grace, It gave me great comfort knowing she was only ever a phone call away. Deb brings such a humanistic approach to an otherwise stressful but exciting but emotionally heavy time in life. She maintains full transparency while also validating and supporting concerns; there was no aspect of the house selling process I felt I couldn't ask Deb about. I'm proud and privileged to have established both a professional and personal relationship with her, one that I'm certain will stand the test of time and would not hesitate to put her in touch with any of my loved ones, you are a league all your own, Deb!

John was my realtor for sale of my house in warren. I couldn’t have asked for a better representative. Simply Selling a house is not what a great realtor does. It also requires promptness,, patience and experience in the applicable market. A good realtor like John can advise on repair contractors if needed, movers and other service assistance. And of course , it requires someone who is a good go between with the other realtor. John did it all. He was always available when I called. He would meet personally whenever needed. And if I had a question, he either knew the answer or researched it for me. If you are thinking of selling or buying. John and his team are really thr best choice by far . I am positive he won’t disappoint you!

John was a critical part of getting to the finish line on our home purchase. Always responsive and providing valuable knowledge along the way so we could keep the process moving. A pleasure to work with! Also very knowledgeable about the area.

We had excellent experience working with John Mangini on the sale of our home recently. With over 20 years of real estate experience, he has an in-depth understanding of the local market and provided valuable insights throughout the entire process. He was always on top of every detail, dedicated to making sure things moved forward smoothly, and offered tremendous help when it came to dealing with the buyer. His professionalism, punctuality, and commitment truly stood out – he was always on time for every meeting and consistently went the extra mile. We would highly recommend John to anyone looking to buy or sell a home.

I highly recommend Deb's services. She is exceptionally friendly and fully dedicated to guiding you through the process of buying or selling your dream home.

We cannot say enough wonderful things about our experience working with Dina to sell our home! From the very first meeting to the final closing day, Dina was the definition of professionalism, expertise, and genuine care. Selling a home can be stressful, but with Dina by our side, the entire process felt smooth, strategic, and even enjoyable. Dina brought a deep understanding of the market, backed by a smart pricing strategy and a beautiful marketing plan that made our home shine. Within days, we had multiple strong offers—well above asking price. Her guidance on staging, timing, and negotiations was absolutely spot-on. But what truly sets Dina apart is her personal touch. She was always available, incredibly responsive, and made us feel like her top priority. She listened to our concerns, answered every question with patience and clarity, and advocated for us every step of the way. If you're looking for a realtor who combines top-tier expertise with kindness, dedication, and unmatched results, Dina is the one. We are so grateful to have had her on our team and would recommend her without hesitation to anyone looking to sell or buy a home. Thank you, Dina, for everything!

Roseann was very helpful and responsive throughout the entire house hunting and home buying process. We really enjoyed having her as our realtor. Her knowledge and attention to detail was wonderful. As first time home buyers, she made sure we were well taken care of. We highly recommend Roseann to anyone.

I honestly don’t even know where to begin because no words can fully express how grateful we are for our real estate agent. From the very start, she was there for us every step of the way—even in the middle of one of the toughest markets we’ve seen in years.

What truly blew us away was her dedication. She showed us the home we ended up buying just 5 days after giving birth. FIVE. DAYS. That level of commitment is something you don’t see every day, and it speaks volumes about how much she cares for her clients.

She guided us through every detail with so much knowledge, patience, and care. Her negotiating skills were absolutely key in helping us land our dream home in such a competitive market. On top of that, she made what could have been an incredibly stressful experience feel seamless and even enjoyable. We closed in just 3 weeks, which still amazes us!

She isn’t just an incredible agent—she’s someone who truly becomes part of your journey, and we’re forever grateful. If you’re looking for someone who will go above and beyond (and then some), you won’t find anyone better.

Debra is an amazing realtor, knowledgeable, patient, and always professional. She took the time to understand our needs and never rushed us through the process. Her calm demeanor and honest advice made buying our home a truly enjoyable experience. Highly recommend her to anyone looking for someone trustworthy and dedicated!

I have worked with Debra on a few different occasions, and she has been a phenomenal realtor. She is always in great communication with me and goes above and beyond to make sure that she is getting exactly what I need. I highly recommend anyone who is looking for a home to buy or rent to contact her.

Gabrielle demonstrated exceptional skill in selling my home. She expertly addressed our fears and concerns, providing nurturing support throughout the process. Her dedication and personalized approach made us feel valued as customers. Gabrielle's outstanding sales expertise, combined with her coaching abilities, truly set her apart. She navigated the complexities of the real estate market with ease, ensuring a smooth experience for us. I couldn't ask for a better saleswoman and coach to guide us through this journey. Superior in all aspects!!!!

We had an outstanding experience working with Roseann! As longtime residents of the area, we truly appreciated her deep knowledge and expertise—she guided us seamlessly through every step of the process. Her years of experience were evident in her sharp insights, proactive communication, and ability to anticipate our needs before we even voiced them.

Whether it was answering our questions at odd hours, negotiating skillfully on our behalf, or simply offering reassurance during stressful moments, Roseann went above and beyond. Thanks to her, what could have been a daunting process felt effortless.

We wholeheartedly recommend Roseann to anyone buying or selling a home—her professionalism, local savvy, and genuine care for her clients are unmatched!

Karina is absolutely wonderful to work with. She took the time to listen, and to understand what my needs were from my new home (transit, bedrooms, storage etc), my price point, and what my aesthetic tastes were. She then targeted homes that fit the profile i was seeking. When touring homes she pointed out defects or things that she noticed that i would want to consider. I never felt pressured to go higher on my offer, nor to go outside of my budget. She was available to make same-day offers even if it meant working late. After my purchase she also helped with referrals to contractors, cleaning people, etc. She is a gem and I highly recommend her.

John Mangini is exceptional as a broker. He is confident because of his years of experience and knowledge of the market. He is calm and so easy to work with. He is diligent and relentless. His attention to detail is unparalleled and his willingness to have as many open houses as was necessary was amazing. I highly recommend him as a listing broker.

Working with John Mangini [NextHome Premier] was truly a game-changer for our home-selling experience. His impressive background in engineering provided a unique edge, especially when it came to evaluating the structural integrity of properties and identifying areas for improvement before listing the property. He organized handymen for touch jobs. His analytical skills and data-driven market analysis were second to none, helping us price our property competitively and navigate market trends with confidence.

What truly made John Mangini stand out was his dedication and willingness to go above and beyond. He not only provided expert advice but personally assisted with cleaning and hauling items to prepare our property for showings/ after close out. This level of care and investment is rare and speaks volumes about this commitment to their clients' success.

His clear, data-backed communication and strategic approach made the entire process smooth and stress-free. Whether you're buying or selling John Mangini is the real estate agent you want by your side. We couldn't be happier and will recommend him wholeheartedly to anyone looking for top-tier service!

John did an outstanding job assisting us with the selling of our home. His expertise on the local market was very instrumental in determining a competitive selling price for our home. He was very involved, always responsive in all the aspects until the closing. He is very polite and a thorough professional. Definitely recommend working with him.

John did an excellent analysis of the market and suggested a strong pricing strategy. Open house foot traffic was excellent and multiple offers were quickly received, at and above asking price. He helped facilitate selling furnishings and a rental agreement so we could remain in the house after closing. He always replied promptly to my requests for info and clearly communicated what I should expect from the process (when to be out of the house or available for the lawyer). I definitely recommend him to other
